About this spot

About

Barra do Sai is an occasional beach break near Guaratuba, where the Saí-Guaçu river mouth shapes the sandbars and helps create rideable banks. Surf conditions are most often sought in May, with the spot working best under northwest winds that are offshore and help keep wave faces clean and groomed. For surfing, it’s primarily a sand-bottom beach-break influenced by the river channel. Waves can be moderate in power with a peeling shape, and both lefts and rights are reported when the sandbars form well. The most workable swell window is around 0.5 to 2.0 meters from the south/east sector, and the spot is described as suitable across all tides. On quality and consistency, surf-forecast-style ratings indicate good quality on better days and only modest consistency overall. Crowding is described as sometimes crowded, so timing around swell and wind windows can matter. Safety is a key consideration: strong currents and rip hazards are specifically noted near the river mouth, with shifting sandbars and submerged debris especially after heavy rains. It’s also recommended to check water quality after storms/tropical rain, and lifeguard coverage is seasonal rather than year-round.

  • NW winds help provide cleaner, offshore conditions
  • River-mouth sandbars can produce longer, more hollow rides
  • Suitable across all tides
